Calories In vs Calories Out isn’t a myth. It’s physics (First Law of Thermodynamics) + physiology. 👉 Eat the same & move more → lose weight 👉 Eat the same & move less → gain weight 👉 Eat more and same level of exercise → gain weight 👉 Eat less and same level of exercise→ lose weight ✅ It should always works. HOWEVER: How much? We don’t know exactly as it depends on your physiology, metabolism, and diet. Everyone is different, so the magnitude can’t be predicted. But the principle holds. That uncertainty is what many exploit to sell you the “diet of the moment” or that magic supplement. At the end of the day: “Body weight change results from an imbalance between energy intake and energy expenditure. That’s a non-negotiable law of physics.” (Hall et al., 2012)
